// A physical font is a concept we have taken from the Java world

// From https://docs.oracle.com/javase/tutorial/2d/text/fonts.html
//
// There are two types of fonts: physical fonts and logical fonts.
// Physical fonts are the actual font libraries consisting of, for
// example, TrueType or PostScript Type 1 fonts. The physical fonts
// may be Time, Helvetica, Courier, or any number of other fonts,
// including international fonts. Logical fonts are the following
// five font families: Serif, SansSerif, Monospaced, Dialog, and
// DialogInput. These logical fonts are not actual font libraries.
// Instead, the logical font names are mapped to physical fonts by
// the Java runtime environment.
